Figure 5-59 shows a map of the downtown area of the picturesque hamlet of Kingsburg. You have been hired by the Kingsburg Chamber of Commerce to organize the annual downtown parade. Part of your job is to plan the route for the parade. An optimal parade route is one that keeps the bridge crossings to a minimum and yet crosses each of the seven bridges in the downtown area at least once.
a. Find an optimal parade route if the parade is supposed to start in North Kingsburg but can end anywhere.
b. Find an optimal parade route if the parade is supposed to start in North Kingsburg and end in South Kingsburg.
c. Find an optimal parade route if the parade is supposed to start in North Kingsburg and end on island B.
d. Find an optimal parade route if the parade is supposed to start in North Kingsburg and end on island A.
